摘要：

氮素是促进水稻物质生产和产量形成的首要因素, 其高效与合理的利用是农业可持续发展的重要保障。培育含有氮高效基因的水稻品种, 充分发挥氮素高效吸收和利用遗传潜力是提高氮肥利用率、减少氮肥施用量的有效途径。本研究从氮素的吸收、转运、再分配和再利用等环节, 选择了OsNR2、OsNPF6.1、OsTCP19、OsLHT1和OsGRF4共5个基因作为水稻氮高效遗传改良的基因组合, 根据已报道的功能位点设计得到与目标基因共分离的基因功能标记, 包括6对等位特异PCR标记和1对InDel标记, 并对70份常规籼稻, 34份常规粳稻和84份太湖资源水稻材料进行了鉴定。结果表明, OsNR2在籼稻中分布较广, OsNPF6.1、OsTCP19、OsGRF4在籼稻中分布较少, 但是均未在常规粳稻中检出; 常规粳稻中仅含有OsLHT1; 同时我们还筛选出2份材料同时含有OsNR2、OsNPF6.1和OsGRF4高效单倍型。本研究开发的功能标记和筛选出的材料为通过分子标记辅助选择方法培育氮高效水稻新品种提供了技术支撑。

Abstract:

Nitrogen is an essential mineral element that affects plants biomass and yield formation, and its efficient and reasonable utilization is an important guarantee for sustainable agricultural. Breeding rice varieties containing high nitrogen use efficiency (NUE) genes is an effective way to increase NUE and reduce the amount of nitrogen fertilizer. In this study, five genes, OsNR2, OsNPF6.1, OsTCP19, OsLHT1, and OsGRF4, were selected from the aspects of nitrogen absorption, transportation, and assimilation. Based on the reported functional haplotype, co-segregated markers were designed. Using six pairs of allele-specific PCR (AS-PCR) markers and one pair of InDel marker, 70 indica rice, 34 japonica rice, and 84 Taihu rice resources were identified. The results showed that OsNR2 was widely distributed in indica rice, while OsNPF6.1, OsTCP19, and OsGRF4 were less distributed. All 34 japonica rice and 84 Taihu rice resources only contained OsLHT1. We also successfully obtained two indica germplasms, which contained OsNR2, OsNPF6.1, and OsGRF4. The functional markers developed in this research and two materials provide technical support for breeding new rice varieties with high NUE through molecular marker-assisted selection (MAS) methods.

Key words: rice, high nitrogen-use efficiency, AS-PCR, InDel markers
